Dynamic roster from terraform current state
===========================================

This roster module allows you dynamically generate the roster from the terraform
resources defined with the `Terraform Salt`_ provider.

It exposes all salt_host resources with the same attributes to the salt-ssh
roster, making it completely independent of the type of terraform resource, and
providing the integration using terraform constructs with interpolation.

Basic Example
-------------

Given a simple salt-ssh tree with a Saltfile:

.. code-block:: yaml

    salt-ssh:
      config_dir: etc/salt
      max_procs: 30
      wipe_ssh: True

and ``etc/salt/master``:

.. code-block:: yaml

    root_dir: .
      file_roots:
        base:
          - srv/salt
      pillar_roots:
        base:
          - srv/pillar
      roster: terraform

In the same folder as your ``Saltfile``, create terraform file with resources
like cloud instances, virtual machines, etc. For every single one of those that
you want to manage with Salt, create a ``salt_host`` resource:

.. code-block:: text

    resource "salt_host" "dbminion" {
      salt_id = "dbserver"
      host = "${libvirt_domain.vm-db.network_interface.0.addresses.0}"
      user = "root"
      passwd = "linux"
    }

You can use the count attribute to create multiple roster entries with a single
definition. Please refer to the `Terraform Salt`_ provider for more detailed
examples.
